BehlkeŽ quality products are worldwide protected by trademark and
patent rights. Nevertheless from time to time we find dubious dealers in the
internet, which offer primitive plagiarisms of our products, of course
without the reliability and the performance of the original. They often look exactly
like BehlkeŽ products, but they are of
lousy quality and are in no way comparable with the originals. Those plagiarisms are of poor performance at best, but often they are
very dangerous too.

To ensure, that you get the original BehlkeŽ product and that you
receive always a true value for your money, we suggest you to check the
following points:

Make sure,
your dealer is an authorized reseller of BehlkeŽ products. In order not
to advertently buy fake products, never accept
dubious deliveries without original labels, without original packing or
without original documentation. Customers should look out also for
the price.Also an exceptionally low price can be an indicator for a
fake.

Make sure,
that the products come always in an originally sealed box with serial
number sticker and final control stamp on the front side of the box.

Behlke
products are directly laser marked or wear alternatively a laser marked,
forgery-proof plastic label, always in white on black (since 2009). Besides the
technical data, the laser marking indicates always an 8-digit serial
number (S/N…) and the manufacturing date and time (M/D…). Additionally,
original products can be identified by at least two quality control
stickers (Q…) with the surnames of at least two Behlke quality
inspectors. The product is only original, if the S/N, M/D and Q data are
plausible in context. In case of any doubt please consult Behlke under
info@behlke.com.

Should you find a new and
unknown “competitive” product on the market and if you are not sure about its
quality, then please check these points:

Has the
“competitor” the necessary production facilities to manufacture
ambitious industrial products at all? Helpful is often a simple view on
the competitors facility address by means of Google Maps, Google Street
View or Microsoft Bing. Be careful, if there is just a family home, a
garage or something similar. Recently we
discovered a businessman in the internet, who has used our
protected trademarksincluding a product
name illegally to sell his
"own" products. He even claims to be the inventor of those high
voltage switches! When we searched his industrial production facility in
Bing Maps,
we found this.
The plagiarism has been thoroughly examined
by our engeneers and here is a brief laboratory report about the
imitated product
(please click here).

Has the
“competitor” the expertise for MIL or HIREL qualified microelectronics
production processes including dry component storage, full component
screening, component tracking, visual inspection etc.?

Does the
“competitor” run a well documented and sufficient quality system? Is it
executed by an independent and certified quality inspector? Is there a real
serial production with quality improvement statistics?

Is the
long-term reliability of the products proven by continuous tests? Does
the “competitor” run extensive climatic and temperature cycling tests by
using sufficient test equipment? Is there any documented burn-in
procedure?

Are the
solid-state products manufactured in a clean and ESD-save environment?

Does the
“competitor” use professional electronic manufacturing technologies and
machineries, such as part component desiccation, plasma treatment,
automated SMD placement, machined vacuum potting etc.?

How long is
the “competitor” on the market? Is there any significant
competence in high-voltage related materials and high-voltage circuit
design? Does he offer OEM products for medical,
military and other safety relevant applications? Are there references?

Has the
“competitor” the expertise to manufacture reliable solid-state switches
in any configuration and in any semiconductor technology for voltages up
to 150 kV and above? Is he able to design reliable solid-state switches
with di/dt’s of 20 kA/us and above?

Has the
“competitor” the expertise to built compact solid-state switches
with 200 kV isolation voltage?

Has the
“competitor” the expertise to manufacture high-voltage solid-state
switches for continuous high power dissipation, e.g. in the Kilowatt
range? Are all kinds of cooling methods available, such as cooling fins,
cooling flanges, water cooling and direct liquid cooling? Has the
competitor the expertise to make heat sinks with sophisticated materials
such as copper compound, graphite and ceramics?

Is the
“competitive” switching module working over the whole temperature range
without any restriction? Has the control signal any influence on the
switching behavior? Is it possible to turn-off higher currents also at
shorter on-times safely and without damaging the semiconductor
stack?

Or becomes the switch unstable at short control pulses?

Are all
the technical data of the “competitive” product comparable to BehlkeŽ
products or is there just a similarity in a few specifications? Does the
competitor specify the exact test conditions for the purpose of
verification?

Does the
“competitor” grants at least two years warranty for his products?

In case of any doubt, please do not hesitate and contact us under info@behlke.com

.

Or simply buy the original directly from BehlkeŽ

, the
inventor of fast high-voltage solid-state switches.
